LM5119 Overview

The LM5119 is a dual synchronous buck controller intended for step-down regulator applications from a high voltage or widely varying input supply. The control method is based upon current mode control utilizing an emulated current ramp. Current mode control provides inherent line feed-forward, cycle-by-cycle current limiting and ease of loop pensation.

LM5119 Key Features

  • Emulated peak current mode control
  • Wide operating range from 5.5V to 65V
  • Easily configurable for dual outputs or interleaved single
  • output Robust 3.3A peak gate drive Switching frequency programmable to 750kHz Optional diode emulation mode Programmable
